Perform Diagnostics

Command:

Test the processor, software and the LMK pairs. Return the LMK check value.

Notes:

The check value is the same as the value returned for the Console V command.

The Host system should time the NC command and generate an appropriate system message if a response is not received within 5 seconds. If an error is detected in the processor, HSM functions are suspended, and no message is returned to the Host.
